Béla Anton Leoš Fleck (born July 10, 1958) is an American banjo player. An acclaimed virtuoso, he is an innovative and technically proficient pioneer and ambassador of the banjo, bringing the instrument from its bluegrass roots to jazz, classical, rock and various world music genres. He is best known for his work with the bands New Grass Revival and Béla Fleck and the Flecktones. Fleck has won 15 Grammy Awards and been nominated 33 times.

In 2020, he was inducted into the International Bluegrass Music Hall of Fame as a member of New Grass Revival.

A native of New York City, Fleck was named after Hungarian composer Béla Bartók, Austrian composer Anton Webern, and Czech composer Leoš Janáček. He was drawn to the banjo at a young age when he heard Earl Scruggs play the theme song for the television show Beverly Hillbillies and when he heard “Dueling Banjos” by Eric Weissberg and Steve Mandell on the radio. At the age of 15, he received his first banjo from his grandfather. During the train ride home, a man volunteered to tune the banjo and suggested he learn from the book How to Play the Five String Banjo by Pete Seeger. He attended the High School of Music & Art in New York City, playing French horn until he flunked and was transferred to the choir, though he spent most of his time on the banjo. He studied the book Bluegrass Banjo by Pete Wernick and took lessons from Erik Darling, Marc Horowitz, and Tony Trischka.
